| Abstract: | Concentrations of HCHs, DDTs and PCBs were determined in the green-lipped mussels ( Perna viridis ), collected from thirteen sites along the Pearl River estuarine zone from July to August 1996. The ranges of HCHs, DDTs and PCBa in mussels were in the ranges of not - detected ～1.1 ng g-1, 9.5～ 191 ng g- 1 and 82.8 ～ 615.1 ng g- 1 (lipid weight basis) respectively. Relative high levels of DDTs and PCBs were found in mussels collected from the mouth of Pearl River. Mus~ls collected from Tsim Sha Tsui Pier (Victoria Harbour) showed the highest contamination of PCBs, while those collected from Hebao Island (Western estuarine zone) had the relative high contamination of DDTs and HCHs. Penta- and hexa-chlorinated PCB were selectively accumulated in Perna viridis. The isomeric composition analysis of residues in mussels from thirteen coastal locations indicated that there were two different PCBs pollution sources in the Pearl River Estuarine zone. |
